Global Temperature Report: July 2010

Second hottest July on record as El Nino fade continues

Global climate trend since Nov. 16, 1978: +0.14 C per decade

July temperatures (preliminary)

Global composite temp.: +0.49 C (about 0.88 degrees Fahrenheit) above 20-year average for July.

Northern Hemisphere: +0.63 C (about 1.13 degrees Fahrenheit) above 20-year average for July.

Southern Hemisphere: +0.34 C (about 0.58 degrees Fahrenheit) above 20-year average for July.

Tropics: +0.48 C (about 0.61 degrees Fahrenheit) above 20-year average for July.

June temperatures (revised):

Global Composite: +0.44 C above 20-year average

Northern Hemisphere: +0.55 C above 20-year average

(All temperature anomalies are based on a 20-year average (1979-1998) for the month reported.)

Notes on data released Aug. 3, 2010:

July 2010 was the second hottest July in the 32-year satellite temperature dataset, with a global average temperature that was only 0.03 C cooler than the record set in July 1998, according to Dr. John Christy, professor of atmospheric science and director of the Earth System Science Center at The

University of Alabama in Huntsville.

Average temperatures for the globe, as well as the northern and southern hemispheres, went up in July despite the continued cooling of the El Nino Pacific Ocean warming event and the apparent transition to a La Nina Pacific Ocean cooling event.

"If you look at how much sea surface temperatures are falling, no one would have predicted this," Christy said.

July 2010 was the second hottest July globally and in the Northern Hemisphere; third hottest in the Southern Hemisphere; and fourth hottest in the tropics.

Compared to seasonal norms, July 2010 was also the 17th warmest of all of the months since the satellite temperature dataset began in December 1978.

The first seven months of 2010 were only 0.07 C (about 0.13 degrees Fahrenheit) cooler than the record set in 1998 during another El Nino Pacific Ocean warming event.

As part of an ongoing joint project between UAHuntsville, NOAA and NASA, Christy and Dr. Roy Spencer, a principal research scientist in the ESSC, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.

The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a "public" computer file for immediate access by atmospheric scientists in the U.S. and abroad.

Neither Christy nor Spencer receives any research support or funding from oil, coal or industrial companies or organizations, or from any private or special interest groups. All of their climate research funding comes from federal and state grants or contracts.

The Global Temperature Report is published monthly by the Earth System Science Center at The University of Alabama in Huntsville, and is provided free of charge to scientists, news organizations, policy makers and others.

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
